Question

Suppose the first strip $A$ is red, second strip $B$ is yellow, third strip $C$ is orange and fourth strip $R$ is silver, from left to right, in a colour coded carbon resistor. What is the value of resistance?

• A. $(24\pm 5\%)\,k\Omega$
• B. $(24\pm 10\%)\,k\Omega$
• C. $(350\pm 5\%)\,k\Omega$
• D. $(350\pm 10\%)\,k\Omega$

Answer 1

Answer: (B)

$(24\pm 10\%)\,k\Omega$

Answer 2

Value of resistance is expressed as $A B \times 10^{\circ} \pm D$
$\therefore$ Resistance $\rightarrow(24 \pm 10 \%) k \Omega$
